Overview
- When symptoms suggestive of peripheral artery disease are present, clinical evaluation along with non invasive testing are enough to establish the diagnosis. Invasive diagnostic studies are anatomic studies that are not used for diagnosis but rather for preoperative evaluation of the anatomy of the vessels.
- The invasive diagnostic studies, which are basically anatomic studies that rely on imaging, include the following:
- Conventional angiography.
- CT angiography
- MRA
- Duplex ultrasound.[1]
Other Imaging findings
Conventional Angiography
- Conventional angiography is considered as the standard in the invasive evaluation of peripheral artery disease.
- It is very accurate in providing detailed evaluation of the structures of the vessels.
- The down sides of conventional angiography are:
2005 ACC/AHA Practice Guidelines for the Management of Patients With Peripheral Arterial Disease (Lower Extremity, Renal, Mesenteric, and Abdominal Aortic)-Recommendations for Continuous-Wave Doppler Ultrasound (DO NOT EDIT)[3]
| Class I |
| "1. Continuous-wave Doppler ultrasound blood flow measurements are useful to provide an accurate assessment of lower extremity PAD location and severity, to follow lower extremity PAD progression, and to provide quantitative follow-up after revascularization procedures. (Level of Evidence: B)" |
2005 ACC/AHA Practice Guidelines for the Management of Patients With Peripheral Arterial Disease (Lower Extremity, Renal, Mesenteric, and Abdominal Aortic)-Recommendations for Contrast Angiography (DO NOT EDIT)[3]
| Class I |
| "1. Contrast angiography provides detailed information about arterial anatomy and is recommended for evaluation of patients with lower extremity PAD when revascularization is contemplated. (Level of Evidence: B)" |
| "2. A history of contrast reaction should be documented before the performance of contrast angiography and appropriate pretreatment administered before contrast is given. (Level of Evidence: B)" |
| "3. Decisions regarding the potential utility of invasive therapeutic interventions (percutaneous or surgical) in patients with lower extremity PAD should be made with a complete anatomic assessment of the affected arterial territory, including imaging of the occlusive lesion, as well as arterial inflow and outflow with angiography or a combination of angiography and noninvasive vascular techniques. (Level of Evidence: B)" |
| "4. Digital subtraction angiography is recommended for contrast angiographic studies because this technique allows for enhanced imaging capabilities compared with conventional unsubtracted contrast angiography. (Level of Evidence: A)" |
| "5. Before performance of contrast angiography, a full history and complete vascular examination should be performed to optimize decisions regarding the access site, as well as to minimize contrast dose and catheter manipulation. (Level of Evidence: C)" |
| "6. Selective or superselective catheter placement during lower extremity angiography is indicated because this can enhance imaging, reduce contrast dose, and improve sensitivity and specificity of the procedure. (Level of Evidence: C)" |
| "7. The diagnostic lower extremity arteriogram should image the iliac, femoral, and tibial bifurcations in profile without vessel overlap. (Level of Evidence: B)" |
| "8. When conducting a diagnostic lower extremity arteriogram in which the significance of an obstructive lesion is ambiguous, transstenotic pressure gradients and supplementary angulated views should beobtained. (Level of Evidence: B)" |
| "9. Patients with baseline renal insufficiency should receive hydration before undergoing contrast angiography. (Level of Evidence: B)" |
| "10. Follow-up clinical evaluation, including a physical examination and measurement of renal function, is recommended within 2 weeks after contrast angiography to detect the presence of delayed adverse effects, such as atheroembolism, deterioration in renal function, or access site injury (e.g., pseudoaneurysm or arteriovenous fistula). (Level of Evidence: C)" |
| Class IIa |
| "1. Noninvasive imaging modalities, including MRA, CTA, and color flow duplex imaging, may be used in advance of invasive imaging to develop an individualized diagnostic strategic plan, including assistance in selection of access sites, identification of significant lesions, and determination of the need for invasive evaluation. (Level of Evidence: B)" |
| "2. Treatment with n-acetylcysteine in advance of contrast angiography is suggested for patients with baseline renal insufficiency (creatinine greater than 2.0 mg per dL). (Level of Evidence: B)" |
